As electric mobility continues to scale, charge point manufacturers and charging network operators require solutions that deliver sustained performance, stand up to demanding daily use and help reduce system complexity over time.


Our all-new RADOX® HPC600 CCS1 CC75 connector is raising the bar for High Power Charging (HPC), with a complete system solution designed for performance, robustness and ease in operation. Combining state-of-the-art cable, connector and cooling technologies, HUBER+SUHNER is enabling improved charging performance, while helping our customers lower their total cost of ownership.

RADOX HPC600 CCS1 facelift

What’s different with this new upgrade?


This new high-power DC charging connector (developed for 600 Amps of continuous charging) has had notable design upgrades that strengthen its performance, including:


  • a reinforced aluminium lever for greater durability
  • an upgraded interface for improved impact resistance 
  • an optimised internal fixation concept to support long-term reliability
  • Integrated bending protection to help extend cable life. 


For users in the field, handling has been improved through a more flexible cable with a reduced outer diameter of 31.5 mm, making the connector easier to use despite its demanding high-power application. 

Smarter cooling with T35 and T36 cooling units


We’ve also introduced two new single-cable cooling solutions: the LWK 24 V T35 with an air-cooled heat exchanger and the WKW 24 V T36 with a liquid-cooled heat exchanger. These charging units are designed to support a single high-power charging cable instead of two, enabling a simpler system layout for charger manufacturers. That means easier integration, reduced system complexity and a clearer fit for applications where one cable per dispenser is the right answer.


The cooling units also bring practical operational value. They were specifically developed to support 600 Amps continuous charging and include a boost mode that automatically increases pressure and fan speed at high temperatures to improve thermal performance. Backward-compatible alarm management and positioning as a replacement path for older single cooling units further strengthen the business case for customers looking to modernize existing charging systems.


Combining these developments in high power charging marks a significant step forward for HUBER+SUHNER expertise in high power charging solutions. While performance still matters, so does uptime, durability, maintainability and ease of integration. These solutions are a result of our deep understanding of what the EV market increasingly demands; high-power charging solutions that work harder in the background so operators and OEMs can focus on reliability at the point of use.


At HUBER+SUHNER, we offer a more complete system approach that connects charging performance with real-world usability and operating efficiency. As the industry looks ahead to the next phase of EV infrastructure growth, we’re proud to be right there alongside them as trusted partners, devising and delivering the solutions for EV charging infrastructure.
